anyone seen this before

I've been asked by a realtor friend to estimate this job for a coming sale. This bathroom is apparently about five years old and these spots started about six months later. I'm thinking exposed metal screws or nails under the marble? Any other ideas? is there another possible cause? the shower floor pitch is also terrible and there is efflorescence on the grout and several low spots. no evidence of a leak. I don't have a ton of experience fixing other's work.

To estimate fixing it or replacing it?

Only one reasonable option, in my opinion.

Based on the lippage, rust penetration, awful looking floor, your estimate should include, complete tear out, and redo only. that's a good job if you can get it.

Rust? I thought those were knots in the wood.

If screw heads are rusting through it means there's no waterproofing over them. As the others have said, rip it out and start over. And talk the realtor into porcelain tile instead of stone.

LOL.....I thought it might be a design feature. Figgured you were referring to the star cracks in the floor....

Rust?

Possibly set with construction adhesive from a caulking gun.

When in doubt, tear it out!

Yes, those are almost certainly rust stains from screws behind the stone. To me, that stone looks like limestone, not marble. Limestone is like a super-sponge, it pulls moisture (and color) from wherever it can get it through capillary action. As others have mentioned, if the screws are rusting, it's clear that the waterproofing wasn't done correctly. I agree that you'll need to start from bare studs on that one, it's not worth saving.

Yep, I agree with the others. There's no repairing it. I'd tear it out or do nothing. Since they are wanting to sell the house, they'll probably find someone that will repair it. Most of the time they won't want to spend the money to do it right. You know how that goes.

Maybe they patched the nail heads with liquid nails, thinking they were going the extra mile.

The rust stains and cracked floor go well with the drilled-into curb! Together they form a trio of failure.

That's what I originally thought, Brian. I saw that and didn't even think about the spots. Thought they were a "Design Feature..."
